WALTER UIEBB, OLE STOCKTON, C.ES.LEFOBNIA SAFETY AUTO SIGNAL.

Application filed November 16, 1923.

To all 'whom t may concern.'

Be itlinown that l, T@Veranst Vilnen, a citizen of the United States, residing at Stochton, county oil bien Joaquin, State oi California, have invented certain new and useful linprovements in Safety flute Signals; and ldo declare the following to be a full, clear, and i exact description ot the same, reiterencc being had to the accompanying drawings, and to the characters of* reference marked thereon, which torni a part ot this application.

rllhis invention relates to improvements in` mechanical signal devices or motor vehicles of all kinds; my principal object being to provide a signal of this general character having an arm adapted to he raised to any of the legally and arbitrarily designated positions at the will of the driver to denote his .intent to turn his l vehicle to the right or the lett, or to stop, the signal boing arranged to be mounted on a rear fender ot the vehicle or similar location so as to be readily visible to any driver behind or in front of the vehicle on which the signal is mounted.

Another obj ct is to provide a simple means for enabling the outline ot the signal arm, and its relative setting when extended, being readily seen in the darli, so that my signal is as eliective at night as in the day time.

'lhe use oit my signai will ot course obviate the necessity ot extending the hand to give signals as is at present commonly done, and which at best is a crude and very often ineiiicient means of giving signals.

A further object of the invention is to. produce a simple and inexpensive device andY yet one whichV will be exceedingly effective for the purposes tor which it is designed.

These objects l accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal ot' the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a perspective outline of an automobile, showing my improved signal in stalled thereon.

Fig. 2 is a vertical section of the signal detached.

Fig. 3 is a cross section of the same, the signal arm being in its closed position.

Referring now more particularly to theV characters of reference on the drawings, the

aerial No. 675,147.

numeral 1 denotes in general an automobile, having rear wheel-,fenders 2, on one of .vhich, preferably the lett hand one, my iniproved signal device is mounted.

This comprises a vertical casing 3, prei;- erably made in two vertical and symmetrical sections suitably connected together, and, provided with horizontal brackets d at its base whereby to attach the same to the tender.

Pivoted in the casing adjacent the upper end and outer edge thereotcn a horizontal pin extending in a plane iongitudinally ot the vehicle is a signal arm 6, adapted to be normally concealed within the casing, the latter having a vertical slot 7 in its outer edge to enable the a m to pass into the casing.

The arm israised from its downwardly projecting and concealed position by moans of a flexible cable or wire 8 Ysuitably at tached at one end to a lug 9 projecting radialiy trom the hub 1() of the arm, said wire leaving the bottom and rear edge of the casing through a protective tube 11 and being run thence to a point where it may be suitably manipulated by the driver. 0n pulling this cable diiierent distances, the arm is raised to the various signal-giving' positions, as indicated in Fig. 2.

rlhe arm is automatically returned from any extended position to which it may have been moved, to its concealed position in the casing when the pull on the cable is re leased by means of a spring 12 of suitable nature, attached at one end t0 the hub 10 and to the casing at the other end.

A resilient bumper block 13 is mounted in the bottom of the casing inwardly of the arm, to 'form a stop for the arm when the latter is returned to the casing by the sprinv.

Mounted in the casing inwardly of the space occupied by the arm is an electric light bulb la backed by a reflector 15, the light being connected in a circuit in any suitable manner.

lihe reflector is shaped and disposed to throw the rays of light from the bulb lengthwise onto the arm when the latter is projected from the casing, the actual source oi' light being invisible. To cause the light to throw onto the sides of the arm and to bring the same sharply into relief without any shadow along the edge farthest from the light, the arm is made wedge-shaped n cross section, with the thin edge :facing downwardly or toward the light, as clearly shown.

F rom the foregoing` description it will be readily seen that l have produced such a device as substantially fullills the objects of the invention as set forth herein.

lVhile this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do notorm a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what l claiin as new and useful and desire to se cure by Letters Patent is:

l. A signal device for motor vehicles slotted to receive the arm and the latter beiinmovably mounted on a vehicle, and an arm pivoted in the Casing and normally concealed therein, one edge of the casing being slotted to receive the arm and the latter being adapted to be rotated about its pivotso as to projectfrom the casing, and a source of light inin'iovably mounted and concealed in the casing independent of the arm, and arranged so that the rays of light will be projected from the slot and onto the arm.

2. A signal device, for motor vehicles comprising a vertical easing arranged to be iinmovably mounted on a vehicle, and an arm pivoted in the casing and normally concealed therein, but arranged to loe swung out ot' the saine at will, and a source of light immovably mounted and concealed in the casing Iand arranged sothat the rays of light will be projected from the slot and onto the arm, the latter being wedge-shaped in cross section with its thinnest edge facing the light, whereby to cause some of the light rays to be thrown against the arm to bring the latter into sharp relief.

3. A signal device for motor vehicles comprising a vertical casing slotted up one edge, an immovable source of light lixed in the casing` and facing the slot, and an arm pivoted in the. casing and facing the slot, and arranged to be swung into and out or the slot, the arm being symmetrically' wedge-shaped with its thinnest edge facing the light, whereby certain of the light rays will be thrown against both sides o1" the arm to cause the same to be sharply outlined both troni ahead and 'behind the signal.

ln testimony whereof I affix my signature.

WALTER WEBB.
